Season 40 is Ken Jennings’s second season behind the lectern as the host of JEOPARDY!, for which he was Emmy-nominated in 2023 for “Outstanding Host For A Game Show.” Jennings and Mayim Bialik officially became the hosts of the show ahead of Season 39 in July 2022, after guest hosting the show in Season 37 and sharing hosting duties for Season 38.

He then went on to appear in several special JEOPARDY! tournaments, including the Ultimate Tournament of Champions in 2005, JEOPARDY!: The IBM Challenge in 2011, the Battle of the Decades in 2014 and JEOPARDY! All-Star Games in 2019.

In 2020, he bested Brad Rutter and James Holzhauer in the ABC special event “JEOPARDY! The Greatest of All Time.”

Jennings is the author of 14 books; “Brainiac,” about his JEOPARDY! adventures, was a critically acclaimed New York Times best-seller, as were his follow-up books “Maphead” and “Because I Said So!” His latest book, “100 Places To See After You Die,” was released in 2023.
